Earlier I answered this (now deleted) question about SMTP configuration. After I answered it, the OP changed the question completely, including my suggested changes and posted the next problem that arose after my suggested solution.
I told the OP so in comments, with the intention of pointing them towards creating a new question with the new problem, because the new wording of the question rendered my answer completely invalid (keeping in line with this Q/A).
Since the OP has been on SF for 8 years and had already earned a solid amount of reputation I assumed that he knows how this site works, but the OP argued that it is still the same topic. Since the OP seemed to be determined to stay on that position I deleted my (now invalid) answer.
After that the OP decided to delete the whole question.
Is there anything I could have done differently?
